Capture/Replay: Use flat map for uniform locations. Similarly to prior changes that change the resource map lookup, this change switches the uniform lookup from an unordered map to a plain pointer lookup. It internally uses an unordered_map of vectors, and caches each vector base pointer whenever a program updates uniform locations. Testing with Manhattan 3.0, this CL decreases the binary size in a Windows/Release build from 6.125MB to 4.413 MB. This is about a 28% decrease. This allows for longer traces and also reduced replay overhead.
